(CNN) - Meghan McCain, daughter of presumptive Republican presidential nominee John McCain, is trying her hand at being a children's author.

The publishing giant Simon & Schuster announced Wednesday that McCain, 23, will write a children's book about her famous father set to be published during the first week of September - the same week as the Republican Party's national convention in Minneapolis.

"I am truly excited about the opportunity to write a children’s book about my father, who is not only a fantastic dad, but also a great American," McCain said in a statement. "This book will offer children the unique opportunity to see the character building events that happened over his lifetime, experiences that led up to his current bid to become the future President of the United States."

Simon & Schuster said it will donate a portion of the proceeds from the book to the Intrepid Fallen Heroes Fund, an organization that aids military personnel and veterans who have brain injuries.

Meaghan McCain has already drawn attention for her writing this year - her campaign blog became a primary season phenomenon.
